What the fuck is white day?
We always celebrate Mothers' Day, Fathers' Day, and Valentine's Day.
Wiki puts it much better:
"In Japan, Valentine's Day is observed by members of the female gender who present chocolate gifts (either store-bought or handmade), usually to a member of the male gender, as an expression of love. The handmade chocolate is usually preferred by the receiver, because it is a sign that the receiving male is the girl's "only one". On White Day, the converse happens: males who received a "honmei-choco" [chocolate of love] or "Giri-choco" [chocolate of courtesy] on Valentine's Day are expected to return the favor by giving gifts, usually more expensive. Traditionally, popular White Day gifts are cookies, sugar candies, white chocolate, marshmallows as well as jewelries, lingerie, and stuffed animals. Sometimes the term sanbai gaeshi (literally, "thrice the return") is used to describe the generally recited rule that the return gift should be two to three times the cost of the Valentine's gift."
We always did V-Day and White Day in my Japanese class in high school.
